Scripts for shooting "Enemy" Prims...

... Yeah, basically, to go along with a weird avatar collection I started.
Basically, fighting cartoon Animal Nations.

I'm still fairly.... New, to scripting, so I'm not sure if I have the abilities yet to even comprehend how to do this.

What I need, is tips/scripts that will allow Object A (Cat Soldier) to identify Object B (Dog Soldier) and "fire" rezzed bullets at it's identified target until it's health depletes to zero.

In other words, if any Dog Soldiers are rezzed along with Cat Soldiers rezzed, they will both identify and fire at each other until one of them dies.

I know, this probably sounds like an odd request, so if I don't make much sense in my request feel free to notify me.

P.S: I already have prim-force affected Health scripts, so I don't need anything regarding health unless it is needed for the target-and-fire.

This isn't odd at all, there are freebie Daleks in world that do just that, place one of each Dalek in world and they search for each and then start firing until one is dead.
